Abstract
A transmission system is proposed for forming a cyclical motion from a rotary motion. Such a gear comprises a cam plate attached to a frame wall. A roller, mounted on a roller lever, rolls on said cam plate. The roller lever is swivelmounted on the rotating part and produces a cyclical motion within the rotating part. The roller is safeguarded by a spring against the cam plate. To compensate for torque fluctuations which are produced owing to the spring contact of the roller on the cam plate, a further cam plate connected to the rotating part is provided, with a spring-loaded roller likewise rolling thereon. The springloaded roller is held on a swivel lever. The shape of the further cam and the spring force acting on the roller are such that torques are produced which counteract the torques which are applied via the roller to the rotating part.
Description
The present invention relates to a kind of transmission device that forms cyclical movement by rotatablely moving, it comprises that a rotating part and at least one make it to be in the actuating linkage of cyclical movement by rotatablely moving, actuating linkage is with suitable power or shape and rotating part co-operation, at this moment act on an inhomogeneous power on actuating linkage, this power produces the moment of torsion of a fluctuation in rotatablely moving.
This transmission device can be indicated in DE-OS3333050.There, rotating part is a disc cam, and an actuating linkage rolls on this cam by a roller that can be rotated to support on this actuating linkage.Said apparatus is used as the operating mechanism of the preceding grippers of paper press, at this moment, by means of the shape of cam, makes actuating linkage do cyclical movement, the rocking-turn campaign of grippers before this motion is used for forming.For actuating linkage is close on the cam all the time, thus actuating linkage is supported on the additional cams, this additional cams and the parallel installation of above-mentioned disc cam, and fixing speed ratio rotation is arranged by disc cam therewith.Actuating linkage is lived as intermediate connector is supported with elastic element, even the size of spring force should guarantee also can make when running up actuating linkage to be close to this disc cam.
Also another tappet roller that can not adopt additional cams and flexibly support, and act directly on the actuating linkage or act on the hinge means that is contained in the actuating linkage back with a spring, thereby avoid making actuating linkage to lift from cam.Here also require the design of spring can guarantee reliably working when machine is made high speed operation will guarantee that promptly actuating linkage keeps in touch with cam all the time.But the result of the elastic force that above-mentioned spring is acted on cam is the moment of torsion that has caused drum shape camshaft, the size of moment of torsion is then relevant with cam type surface and spring force, it both can the conrotatory veer, also can be reverse rotational direction.These moments of torsion are superimposed upon on the moment of torsion of drive motor, and thereby make moment of torsion produce fluctuation, the moment of torsion of this fluctuation can make a difference to entire machine, evokes the vibration of frame or rotating part sometimes.This fluctuation moment of torsion not only can cause by spring, can also be caused by the quality that actuating linkage makes it to do cyclical movement by those.Owing to the irregular motion of quality produces inertial force, the inertial force reaction is on cam.
The objective of the invention is to compensate owing to form the torque ripple that cyclical movement produces from rotatablely moving.
The way that reaches this purpose is, the device that another carries out cyclical movement is set, it and rotating part or the rotating part associated that interrelates by rational shape with another and this rotating part, this device makes it to apply a power that is used for the compensation torque fluctuation by means of a spring on rotating part.
According to device of the present invention, the accurately fluctuation of compensation torque, and therefore make the formed cyclical movement that rotatablely moves not have reaction, thus guarantee the machine smooth working.
Advantage of the present invention is that the spring that produces equilibrant force in the device is not to act directly on the rotating part, but masterpiece can be used on other the part yet, for example can act on the gear that rotating part is meshed therewith.This gear also can be for example be rotated with half of rotating part rotating speed.In this case, the cyclical movement of this device must be carried out with double frequency.
Other structure of the present invention is, disc cam of installing on rotating part, actuating linkage rolls on cam by the roller of spring-loaded, fluctuation for compensation torque, another disc cam of dress on rotating part or other part, another actuating linkage rolls on this disc cam by a roller, and this roller loads with spring force by means of a spring, is anti-phase by the moment of torsion of these two cam action on rotating part.
This means, cyclical movement is spring-loaded the actuating linkage of being close to it by a disc cam and one and forms, another disc cam is housed on camshaft, on it, roll across another equally by spring-loaded actuating linkage, the spring performance line of the shape of this another cam and last described spring should be elected as to make by actuating linkage formed two torque ripples on axle and disappears mutually each other.
Cam is rotated, and actuating linkage fixed installation, this fix with cam and actuating linkage to rotate around cam be the same.In addition, its structure also can be, a cam is fixed, a cam rotation, and the situation of actuating linkage is then corresponding with it.
Other content of the present invention is, is provided with that spring compensates because inhomogeneous active force and the torque ripple that causes in the irregular motion of certain rotating speed district quality.
This means the torque ripple that the spring in the said apparatus produces in the time of can also compensating owing to the quality acceleration.The quality of accelerated motion for example is the hinge means that is contained in the actuating linkage back, or the mechanism of implementation cycle property motion.Because the caused torque ripple of these quality can be determined under some rotating speeds with simple method, and design cam type surface according to the variation of moment of torsion.The present invention can both compensate the torque ripple that the quality acceleration causes because the torque ripple that spring force causes also compensates with a unique cam type surface.Can certainly compensate the dissimilar torque ripple that is produced respectively with a plurality of compensation devices.
The present invention can be applied in the mode with advantage in the conveying cylinder of paper press, at this moment the roller lever on the conveying cylinder that is contained in rotation that rolls on the hard-wired disc cam one, the motion of roller lever has caused one in order to carry the grippers support that will carry out materials printed to extract and transmitting movement, and/or close or open the motion of holding tooth in the month, in addition, the disc cam that another rotates with cylinder also is housed, on this cam, roll across another actuating linkage of a band roller, it is by a spring-loaded that is supported on the frame, so that carry out torque compensation.The motion that is contained in the grippers support on the grippers cylinder is a kind of reciprocal oscillating motion, and it is normally formed by cam.Equally, the holding paper motion itself also realizes with a cam.The actuating linkage that links to each other with the grippers support is pressed on the cam by a powerful backspring, and the roller of actuating linkage and cam are thrown off when avoiding machine to make high speed rotating.
Describe the present invention in detail by embodiment below.
Wherein:
Fig. 1 produces oscillating motion and has the transmission device of torque compensation,
The sectional view of Fig. 2 transmission device shown in Figure 1,
The transmission device of grippers before Fig. 3 paper press,
Fig. 4 represents the plotted curve of torque compensation.
Identical part is represented with same label.
Can see that from Fig. 1 and Fig. 2 the transmission device that produces oscillating motion is contained on the cylinder 2, cylinder can be rotated to support in the chassis wall 1 by bearing 3.This cylinder is for example by a driven by motor that is positioned at the other end of not representing in the drawings.On chassis wall 1, fixed a disc cam 5 with one heart with axle 4 and cylinder 2.Cam 5 is fixedlyed connected with chassis wall 1, and a hole is arranged at its center, makes between axle 4 and the cam 5 and leaves a gap.Roller 6 rolls on cam 5, and it is fixed on the cylinder by roller lever 7.The spring 22 of cylinder 2 inside forms an impacting force between roller 6 and cam 5, this power should be enough big, and roller can not lift from cam during with assurance cylinder high speed rotating.Profile by means of cam makes roller lever 7 15 do oscillating motion around the shaft.Some part in cylinder can be for example handled in this motion.The impacting force that is produced by pressure spring 22 is not only towards cam center, and it also produces along circumferential than high pulling torque according to the profile of cam, and this moment of torsion is superimposed upon on the driving torque on positive and negative both direction.In order to compensate the moment of torsion that this is applied up, on axle 4, establish a disc cam 8, so it is with cylinder 2 rotations.Roller 9 moves on this cam, and it is bearing on the chassis wall 1 by hinge lever 10.Spring 11 acts on power on the roller 9, and this power is pressed on roller 9 on the cam 8.Having that end of roller, spring 11 to be bearing on the bearing 14, bearing 14 links to each other with hinge lever 10.Spring 11 then is contained in the thrust supporting 12 at the other end on the other side.Guide rod 13 between thrust supporting 12 and bearing 14 can prevent that spring 11 is crooked.Select the profile of cam 8, make because the moment of torsion that power produced of spring 11, and because the caused moment of torsion of the impacting force of roller 6 on cam 5, opposite sign but equal magnitude.Therefore on driving torque, no longer be superimposed with the moment of torsion of fluctuation.Except that driving torque, only need overcome less constant friction torque.
Fig. 3 has schematically illustrated a transmission device that is used for the preceding grippers of paper press.For example known in " the Heidelberg communication 4/36 " by Heidelberg printing press joint-stock company documents and materials place, from paper buttress, fetch and should import a piece of paper that printing press goes in accurate back, location from the static print speed printing speed that enters, and be submitted to the grippers of printing cylinder.Conveying cylinder with the press speed rotation is set for this reason.In this cylinder, have one can be with respect to the grippers support of drum speed motion, its motion in accepting paper process is opposite with the direction that rotatablely moves of conveying cylinder, so it is fixed.The speed of the motion of this grippers support and conveying cylinder adapts subsequently.So paper accelerates to print speed printing speed gradually, and under grippers support and the synchronous operated situation of printing cylinder, be passed on the printing cylinder.The motion of grippers support is handled by a cam.
The mechanism that handles the grippers support is described below by Fig. 3.There is a roller lever 7 conveying cylinder 20 inside in rotation, and it is bearing on the hinged support 21 that is loaded in the conveying cylinder 20 pivotally.One end of roller lever 7 is equipped with a roller 6 along fixed disc cam 5 operations, and its other end links to each other with grippers support 23.Grippers bracket by hinges supporting 21 is contained on the conveying cylinder 20 rotationally.Pressure spring 22 acts on power on the grippers support 23, and this power is pressed against on the cam 5 roller 6.Because rotatablely moving of conveying cylinder makes grippers support 23, even the grippers 25 that also is contained in above it arrives paper 19 places that send into via defeated paper platform 18.The leading edge of paper 19 leans against on the block 16, and when turning over away, block 16 received by the grippers support, that is to say, caught the leading edge of paper by the rotation of hinge lever 26, until it is passed to the grippers 24 of printing cylinder 17 from conveying cylinder 20.The kinetic torque ripple of grippers support by being bearing in the roller 6 on the cam 5, is superimposed upon on the driving torque of conveying cylinder.Can adopt as corresponding torque compensation device among Fig. 1 and Fig. 2, compensate exactly, a roller that is spring-loaded and produces corresponding moment variations is arranged on the cam by the cam of not representing among additional this figure.In order to determine the required cam type surface of compensation torque, can for example measure the torque ripple that is produced by the grippers holder device, and, calculate the cam type surface of spring force and design compensation device according to measured thus change in torque with a torductor.
Compensation device not only can compensate the torque ripple that produces owing to certain cam type surface, and can compensate because quality is quickened caused torque ripple.
Fig. 4 has represented the situation of this stack fluctuation moment of torsion.Y coordinate among the figure is represented moment of torsion, and abscissa is represented the corner of solid of rotation rotation one whole circle.Represent the moment of torsion that fluctuates with MI, it causes owing to spring-loading roller is pressed on the cam.Have a constant moment to be superimposed upon on the moment of torsion of fluctuation, this permanent moment for example causes owing to frictional force.Moment MIb is that the acceleration and the deceleration of quality causes that its same purpose is on rotating part.In order to compensate this two moment MI and MIb, on rotating part, install cam with certain profile, it produces on rotating part and presses the moment of torsion of MK curvilinear motion under the effect of a spring-loaded roller.The variation of moment of torsion MK is corresponding with the summation of two moment of torsion MI and MIb.
Except reducing maximum driving torque, the significant advantage of this torque compensator is to avoid producing torsional vibration, this torsional vibration can produce in the transmission device between drive motor and the rotating part, and torque ripple is introduced by this rotating part.This torsional vibration may excite the vibration of entire machine, and now by the simple compensation device of said structure, this vibration is avoided.
Among the represented embodiment, it is fixed that a disc cam is arranged in Fig. 1 and Fig. 2, is rotatably mounted and be used for the disc cam of compensation torque fluctuation.Certainly, these two cams all can be rotated, and rolling wheel support is hard-wired, otherwise or, cam is fixing, and roller is and is rotatably mounted.
